Description

Drill rod detection device

Technical Field

The invention relates to the technical field of construction machinery, in particular to a drill rod detection device.

Background

The soil conditions of the foundation are surveyed before the building construction, and the soil conditions are known. The engineering technicians can detect the hidden structure condition in the soil layer or estimate the allowable bearing capacity of the soil layer according to the hammering number required by the drill rod entering the foundation to be detected for a certain depth. Therefore, the number of hammering required to enter the ground to a specified depth needs to be accurately recorded during the drilling process. The existing drill rod detection needs to manually lift the steel hammer and then release the steel hammer, so that the drill rod is hammered by a free falling body to gradually go deep into a foundation soil layer to be detected, the worker is extremely easy to fatigue by repeatedly lifting the steel hammer, and meanwhile, the hammering number needs to be manually recorded. The operations greatly increase the workload of workers, and the situation that manual counting is inaccurate due to negligence of operators often occurs, so that the obtained data is inaccurate, and engineering technicians cannot accurately judge the real situation of the ground geology.

Disclosure of Invention

Aiming at the defects in the prior art, the technical problem actually solved by the invention is as follows: how to provide a can carry out the borer of hammering and visit device automatically.

In order to solve the technical problems, the invention adopts the following technical scheme:

a drill rod detection device comprises a drill rod and a guide frame, wherein the drill rod comprises an inserted scale rod and a hammering guide rod which are coaxially arranged, the diameter of the inserted scale rod is larger than that of the hammering guide rod, the guide frame is sleeved on the inserted scale rod, the inserted end of the inserted scale rod penetrates through the guide frame, the guide frame can be in sliding fit along the length direction of the inserted scale rod, a hammering disc is sleeved on the hammering guide rod, the lower surface of the hammering disc is abutted against one end, far away from the inserted end, of the inserted scale rod, the hammering disc is fixedly connected with the hammering guide rod, a steel hammer is sleeved on the hammering guide rod and positioned above the hammering disc, the steel hammer can be in sliding fit with the hammering guide rod along the length direction of the hammering guide rod, a through hole extending along the length direction parallel to the inserted scale rod is formed in the hammering disc, a rotating shaft is arranged in the through hole, two ends of the rotating shaft are rotatably, the projection of pivot along hammering guide bar central line direction is located the steel hammer outside along the projection of hammering guide bar central line direction, fixedly connected with ejector pin on the axle body of pivot, the ejector pin is rotatory in the through-hole with can revolute axle central line direction, the central line of the central line perpendicular to pivot of ejector pin, when the central line of ejector pin is on a parallel with hammering guide bar central line, the projection of ejector pin along hammering guide bar central line direction is located the steel hammer outside along the projection of hammering guide bar central line direction, the length of ejector pin is greater than the minimum interval between pivot to the steel hammer, install on the hammering dish and be used for driving pivot pivoted driving motor, driving motor can make the ejector pin conflict move and provide drive power along hammering guide bar central line direction towards keeping away from hammering dish direction at the steel hammer lower extreme through the pivot.

The invention drives the rotating shaft to rotate through the driving motor, drives the ejector rods to rotate together through the rotating shaft, enables the ejector rods to abut against the lower end of the steel hammer and start to rotate towards the direction far away from the hammering disc along the central line direction of the hammering guide rod, so that the ejector rods continue to rotate after the steel hammer is jacked to a certain height, when the central line of the ejector rods is parallel to the central line of the hammering guide rod, the ejector rods are separated from the steel hammer, the steel hammer freely falls down to hammer on the hammering disc, because the lower surface of the hammering disc abuts against one end, far away from the insertion end, of the inserted scale rod, the inserted scale rod is inserted into a soil layer to be surveyed through the hammering disc by the steel hammer, and the operation is repeated, the ejector rods can continuously jack the steel hammer and then release the inserted scale rod to fall. Therefore, the invention controls the rotating shaft to drive the ejector rod to rotate through the driving motor, thereby realizing the automatic jacking of the steel hammer and ensuring the consistent jacking height each time, greatly reducing the workload of workers and avoiding the condition that the workers are easy to generate fatigue after long-time operation.

Further, still install rotary counter on the hammering dish, rotary counter's measuring shaft with the pivot transmission is connected in order to be right the pivot rotates the number of weeks and counts, still install the display screen on the hammering dish, rotary counter's the signal output part is connected with the signal input part electricity of display screen. The existing drill rod probe mostly adopts manual counting, and the counting staff is easy to neglect in work, so that the counting is inaccurate. When the pivot drives the rotatory a week of ejector pin, the ejector pin can put down the hammer jack-up once, makes the hammer carry out a hammering to the hammering dish, consequently, the measuring spindle through the rotary counter rotates the number of weeks and counts, can learn the number of times that the hammer hammered to the hammering dish, and such counting method is more high-efficient, accurate than artifical count, provides accurate reliable data support for engineering technical staff surveys the foundation soil layer.

Further, the leading truck includes the positioning disk of circular structure, has seted up the guiding hole along its central line direction on the positioning disk, insert the scale rod and pass in the guiding hole and along its central line direction rather than sliding fit, the positioning disk and towards in one side of hammering dish is installed the bubble spirit level on the surface, and the edge of positioning disk is provided with at least three supporting legs that are used for carrying out the support to the positioning disk around the even interval of positioning disk central line direction. The leading truck is used for the support of inserting the scale bar, prevents that it from appearing the slope, can adjust the horizontal angle of whole support through the bubble spirit level.

Furthermore, the hammering dish is formed with the base towards protruding on inserting the one side quotation of scale bar, and the base butt is in insert the scale bar and keep away from its one end that inserts the end, the projection of base along hammering guide bar central line direction is located the through-hole is outside along the projection of hammering guide bar central line direction. Through set up the base on the hammering dish, consolidate the hammering dish, can play the firm effect of support to the hammering dish on the one hand, on the other hand can reduce the impact damage that the steel hammer repeated hammering dish led to the fact to the hammering dish.

Compared with the prior art, the invention has the following beneficial effects:

1. according to the invention, the rotating shaft is driven by the driving motor to rotate to drive the ejector rod to jack up and put down the steel hammer, so that the steel hammer can hammer the hammering disc, and the inserted scale rod is driven to be inserted into the foundation soil layer to be surveyed, thus the workload of workers is greatly reduced, the steel hammer can automatically hammer the counting disc, and the condition that the workers are easy to fatigue after long-time operation is avoided;

2. the invention also arranges a rotary counter on the hammering disk, and the rotary counter records the rotation times of the rotating shaft, thus the hammering times of the steel hammer can be accurately obtained.
